Warrick DFB1A0K000006 Level Control

The Warrick DFB1A0K000006 is a professional-grade dual-function level control designed for heavy-duty HVACR and boiler applications. This open-board conductivity-based liquid level control operates on a 120VAC primary voltage and is engineered to manage two independent functions: a low-water cutoff (LLCO) and a secondary single-level or differential control, such as high-level alarm or pump-up/pump-down service. Built for reliability in turbulent environments, this specific model features a 6-second time delay on decreasing levels for the H-L function, effectively eliminating nuisance tripping caused by wave action or surface agitation. As a solid-state liquid level relay, it utilizes a 12VAC secondary circuit to the probes, minimizing electrode plating and ensuring long-term sensing accuracy. The unit provides high-performance SPDT dry contacts rated for 10A at 120VAC, making it a drop-in solution for contractors requiring UL 353 limit control compliance in steam boilers, food service equipment, and industrial reservoirs.

Key Benefits for Technicians

• Dual-Function Versatility: Simultaneously manages low-water cutoff and high-level alarm or pump control on a single board to save enclosure space.
• Anti-Turbulence 6-Second Delay: Prevents rapid relay cycling and equipment wear in applications with unstable liquid surfaces.
• Conductivity-Based Precision: Solid-state sensing with a 12VAC probe voltage ensures safety and high-sensitivity liquid detection.
• Standardized Installation: Features 1/4 inch male spade terminal connections for fast wiring and easy field replacement of legacy Warrick level controls.

Common Questions Regarding This Part

How do I wire the Warrick DFB1A0K000006 for single-level versus differential service?
For single-level service, such as a high-level alarm, the sensor is typically connected to the H terminal. For differential "pump down" or "pump up" control, you utilize both the H (High) and L (Low) terminals to establish the operational deadband between your probe tips.

Which technical applications are best suited for a 6-second time delay?
The 6-second time delay is optimal for large boilers, commercial dishwashers, or tanks where rapid water intake or mechanical agitation causes sloshing. The delay ensures the relay only trips when the level has truly receded below the probe for a sustained period.

Does this level control support secondary voltage variations?
The DFB1A0K000006 is a 120VAC level controller. Ensure your input power matches this requirement; however, the secondary sensing circuit operates at a safe 12VAC to prevent electrolysis and scaling on your probe electrodes.
